My husband is an American.
I don’t care about nationality … but I think Japanese and American are not same, of course.

I’m not sure these are because of the nationality, but some are … I assume.

My husband likes shopping. (he doesn’t know the word ‘saving’! ... I call him 'a minister of shopping!' when he makes a shopping list.)
He uses a lot of paper products. (My mother was so surprised when she saw how many tissues he used to wipe his mouth at the first time ... but finally she laughed since it was always not a little.)
He measures things, for example ― coffee, cocking time, things like that, which I think ‘about’ is OK. (he needs a same spoon every time to make coffee.)
He needs many tools to do thing. (we have thousands of screwdrivers ... I feel.)
He likes meat.
He loves bread. (this makes me so easy to make him happy without any cocking!)
He likes to do everything together.

Oh, I forgot one more big thing.
He loves Diet Cokes ... it is well-known for friends, business people ... He orders even at a French restaurant with French companies! It embarrasses me!

Maybe because he is a man, maybe because he is he.

Sorry, it is very boring story.
I planed to write it funny way … but this is a just boring story.
